• What is the cause and solution for SAP error message RSDD_ZA399 - System time for TREX and NetWeaver not in sync. See SAP Note 1755079. ?

  The SAP error message RSDD_ZA399 indicates that there is a synchronization issue between the system time of the TREX (Text Retrieval and Extraction) server and the NetWeaver application server. This can lead to various issues, particularly in scenarios where time-sensitive operations are performed, such as data retrieval and processing.
  Cause:
  The primary cause of this error is a time discrepancy between the TREX server and the NetWeaver application server. This can happen due to:
  
  Different Time Zones: The servers may be configured to operate in different time zones.
  Clock Drift: The system clocks on the TREX and NetWeaver servers may not be synchronized, leading to a drift over time.
  NTP Configuration: If Network Time Protocol (NTP) is not properly configured or not functioning, it can result in time discrepancies.
  
  Solution:
  To resolve the RSDD_ZA399 error, you can follow these steps:
  
  
  Check System Time: Verify the system time on both the TREX and NetWeaver servers. Ensure that they are set to the correct time and time zone.
  
  
  Synchronize Clocks:
  
  If you are using NTP, ensure that both servers are configured to synchronize their clocks with a reliable NTP server.
  You can manually set the time on both servers to ensure they match.
  
  
  
  Restart Services: After synchronizing the time, you may need to restart the TREX and/or NetWeaver services to ensure that they recognize the updated time settings.
  
  
  Monitor Time Drift: Implement monitoring to ensure that the time remains synchronized over time. This can help prevent future occurrences of the issue.
  
  
  Consult SAP Note 1755079: As mentioned in the error message, refer to SAP Note 1755079 for any specific recommendations or patches that may be applicable to your version of SAP.
